TWO-HAND CONTROL.

\ This invention relates to controls for the operation of machines such as power pressing machines, in the use of which rapid operation is desirable and yet which without the provision of some safety means involve some risk of injury to the operator intent upon efiicient manipulation.

Previously, presses of this type have been operable by the manipulation of a single control handle'in more or less direct connection with the motor starting switch, the motor upon completion of the starting circuit causing the-heated pressing members of the machines to close one upon the other.

" in In this type of machine, capable of actuation by one hand only, leaving the other free, it is possible for the operator, attemptthe lower member while the upper member is advancing into pressing engagement (should the safety uard for some reason fail to operate) to lave her hand caught and injured between the members.

Itis the object of this invention to rowide control means for such a machine, w ich will consist of a pair of interlocked handles requirin simultaneous actuation for settin the mac ine into motion and widely spaced thereon so as to require extension of both, arms of the operator for actuation; thus. make it practically impossible to have 0I1B\ of her hands in the danger zone during movement of the pressing members.

This invention will be readily understood 35 from the following descri tion and accompanying drawings in whic Fig. 1 is a side elevation of a laundry pressing machine embodying my invention; Fig. 2 is a detail, showing a part of the operating mechanism for the control switch employed, part of the switch casing being broken awa to show interior construction; Fig. 3 is a orizontal section in the plane of line 33 of Fig. 1, the outline of the overlying table of the 7 machine being shown in broken line for the purpose of disclosing the position. of the control mechanism on themachine; Fig. 4 is a section along theline 44 of Fig. 3; Fi 5 is a section along the line 5-5, Fig. 3, an Fig. 6 is a section along the line 6-6 of Figs. 3 and 1.

In the drawin bed and frame 0 the machine, the principal parts otwhich are the pressing members 2 and 3 (shown in engaged position) the not shown.

an open position.

1 indicates generally the .invention, but actuated by the motor 4. The

motor controller is in the switch box 5 and includes the contact members 6 for closing the circuit which will start the motor to cause the member 3 to be raised, and the contact members to similarly cause a lowering 05 of the member 3 into engagement with the member 2. After completion of the o ration initiated by closin of either ai the pair of switch members escribed the motor is automatically stopped by a timed switch The manually controlled switches are *operable primarily through a mechanism consisting of the link 8, the bell crank 9 and the rod, 10 terminating at the front of the machine in a handle 11, the mechanism being retained in either of its normal positions by the spring 12. The functioning of this mechanism is obvious by reference to the I Fig. 1, inward movement of the handle 11 causing contacting of the members 6 and resulting in opening of the pressing members of the machine from the position shown, or outward movement closing the press from The. rod 10 carries fixed upon it the two conically surfaced collars Band 14 and is slidably mounted upon the lower surface of the table 15of the machine in the bracket 16. Pivotally mounted at 17 upon the bracket 16 are the latch levers 18 and 19 spring urged towards the collars 13 and 14 respectively as appears in Fig. 3. It will be noted. that the handle 11 is positioned at the left side of the machine convenient to the left hand of the operator; upon the right side of the machine is a similar handle 20 mounted upon a rod 21 in connection at its innenend with an arm on the plate 22 which is pivotally mounted at 23 upon the under surface of the table 15, and is provided with two arcuate slots as shown in Fig. 3.

Suitably connected pivotally with the latches 18 and 19 are rods 24 and 25 which extend across the machine beneath the table 15, each into its corresponding slot u on the late 22. It will be noticed that t e slots. mm with the rods 24 and 25 lost motion connections between" the late 22 and the latches 18 and 19 so that w en the handle 20 her to be moved forwardly and thereby produce an opening operation of the machine.

7. In a machine of the character described, a hand operable control member movable rearw-ardly to produce a closing operation of the machine and movable forwardly to produce an opening operation of the machine, latch means for controlling rearward movement of said control member, latch means for controlling forward movement of said control member, and a single hand operable control member for controlling both of said latch means, said latch control member mit rearward movement of said first men-;

tioned control member and said latch member being movable forwardly to release said second mentioned latch means and thereby permit forward movement of said first mentioned control member.

In testimony whereof I hereby aflix my signature.
